SET-UP & OPERATION
Installing PageFirst Sensor
(optional)
This 975 can interface with an independent classroom paging system.
When a page is broadcast, all audio from the system is muted, ensuring
important school-wide messages are not missed. Please note that PageFirst
is not compatible with telephone or IP-based paging systems.
How it works:
1. PageFirst sensor clip is hung around a lead wire attached to the
classroom paging speaker.
2. The clip is hard-wired to the amplifier.
3. As a page is broadcast, the sensor clip detects the audio signal through
induction and immediately mutes the amplifier.
4. When the page is over, the audio from the amplifier returns to normal
volume level.
USING ALERT NOTIFICATION
If your building is equipped with an alert notification system, you can use
the Flexmike to send an alert. This activates the contact closure function on
the 975, which external systems use to perform a prescribed action, such as
notifying the appropriate parties of a classroom alert.
How it works:
1. To send an alert, simultaneously hold down the volume up and volume
down buttons on the Flexmike for three seconds.
